1 Fixed missing SSL libs for --libs output
3 Re-established OID record syntax application-xml. Nobody should use it
4 but we don't want to change soname because of this symbol being absent.
8 YAZ' RPM spec works for both SUSE Linux Enterprise and RedHat Fedora.
10 Added member named_result_sets for init handler struct for the GFS. This
11 allows a server to disable named result sets.
13 Removed OID record syntax application-xml.
15 Added support for rule-based transliterator for ICU wrapper of YAZ.
17 Fixed bug #1902: yaz-icu XML output.
19 Make YAZ checks Emacs friendly.
21 BITSTRING value shows value. Bug #2346.

27 Allow combined single char options (again) for YAZ' options function.
29 Utility yaz-marcdump got option to display YAZ version (-V).
31 Allow YAZ to use ICU 3.4.
33 Added new ICU test case which illustrates removal of diacritics.
37 Fixed Fixed test that makes VERSION_SHA1 appear on dist versions too.
41 For configure, using option --without-xml2 also disables Libxslt/Libexslt
44 Fixed bug #2352: yaz-marcdump crashes for certain record.
46 Added man page 'bib1-attr' which includes list of common Bib-1 attributes.
48 Added support for Danmarc2 to UTF-8 conversion.
50 Added support for ISO5426 to UTF-8 conversion.
52 zget_InitRequest/zget_InitResponse returns GIT SHA1 hash as part of
53 implementation version.
55 Function yaz_version returns GIT SHA1 hash for parameter sha1_str.
59 ZOOM C now only fires one ZOOM_EVENT_SEARCH per search-task. Previously,
60 ZOOM_EVENT_SEARCH was fired for each searchRetrieve Response received.
62 ZOOM C now interprets databaseName option for ZOOM connection as path
65 Windows version bundled with Libxml2 2.7.1 / Libxslt 1.1.24 / ICU 4.0.
67 Fixed CCL to RPN/PQF conversion which could result in invalid PQF.
69 Dummy Libxml2 types no longer defined in headers of YAZ'.
71 Fixed memory violation for ZOOM C - could occur when SRU diagnostics was
76 Various ODR chapter fixes.
78 Windows version uses libxml2 2.6.32+, libxslt 1.1.23+ and ICU 4.0.
80 Added missing source for Windows compilation, mutex.c.
82 Fixed compilation of YAZ for Visual Studio 2008. Bug #2256.
84 For SRU connections in ZOOM all records up to "count" are now fetched.
86 Fixed crash in generic frontend server (and yaz-ztest) which occurred
87 in Windows due to bad error handling for Libxml2.
89 Added facility for sending arbitrary records (ASN.1 any) using
90 ZOOM C's Extended service update. Patch by Sam Reynolds.
92 New options for ZOOM C's connection, logapdu which makes ZOOM log
97 YAZ uses GNU TLS without the OpenSSL compatibility wrapper.
101 Fixed memory violation that could occur when decoding UTF-8. This bug
102 was only present in 3.0.30 of YAZ.
104 --- 3.0.30 2008/06/06
106 Implemented SSL sockets using GNU TLS. OpenSSL is still supported, but
107 GNU TLS is used by default (if found).
109 yaz-ztest returns OPAC records if a client asks for OPAC.
111 Improved speed of MARC-8 encoding.
113 Added support for lossy and loss-less MARC-8 encoding.
115 Changed yaz_record_conv_record to be reentrant for XSLT conversions.
117 Added new Windows Service wrapper (sc).
119 yaz-client's itemorder command may now send a file.
121 Fixed yaz-marcdump to allow the use of NS prefix for record element.
123 Added new function yaz_log_xml_errors.
125 Allow (but warn) unknown XML attributes in MARCXML parsing.
127 Handle G1 sequneces in MARC-8 decoding. Bug #2115.
129 The UTF-8 to MARC-8 conversion now uses a different set of characters
130 for Greek symbols. Bug #2120.
132 --- 3.0.26 2008/02/21
134 Added yaz_daemon (daemon.h).
136 Fixed bug #2068: pkg-config trouble
138 Fixed bug #395: ZOOM_record / OPAC record encoding problems.
140 --- 3.0.24 2008/01/28
142 Document --with-xml2 option.
144 Added OPAC XML XSD (etc/opacxml.xsd).
146 Allow glob mask for name attribute in retrieval element for the
147 generic frontend server's retrieval facility.
149 Changed yaz_poll_poll to return yaz_poll_except for all returned events
150 except POLLIN/POLLOUT.
152 Fixed error handling in cs_listen. Bug #2037.
154 --- 3.0.22 2008/01/20
156 Fixed version in yaz/yaz-version.h.
158 Fixed bug #2027: Crash when closing connection.
160 Changed configure so that ICU support is only enabled if only ICU
161 and Libxml2 is available (because the ICU chain is XML based).
163 --- 3.0.20 2008/01/15
165 YAZ now makes ICU utilities for Windows. A separate DLL, yaz_icu3.dll,
166 is built. Only this DLL depends on the ICU runtime.
168 yaz-ziffy is no longer part of YAZ. It is distributed separately by
169 Index Data because ziffy's license is GPL2 rather then 'Revised BSD'.
171 Changed license of CCL module to 'Revised BSD'. After consultation with
172 remaining members of the original EUROPAGATE consortium, we are re-issuing
173 the CCL module without a separate license. The software was developed by
174 Index Data as part of a research project. The special license was included
175 to help feed usage information back to the project consortium to support
176 project evaluation. At this time, the project consortium has long-since
177 disbanded, and the majority of the original principals have retired. At the
178 same time, we have significantly modified the software during the following
179 years, to the point where very practically no original code remains. To
180 simplify re-use of the software, we have contacted those members of the
181 consortium who could be reached, and agreed to re-issue the module as a
182 proper part of the YAZ package.
184 Tcl scripts uses /usr/bin/tclsh as preferred shell.
186 CQL closer to being version 1.2 compliant. CQL also allows free-form
187 terms, such as 'title=a b', and thus, make the CQL parser more CCL-like
190 Fixed bug in ZOOM_options_getl WRT setting of parameter lenp. This
191 bug could make Extended services handling crash in the ZOOM layer. This
192 bug was only present in YAZ 3.0.18.
194 --- 3.0.18 2007/12/19
196 ziffy uses YAZ' options rather than getopt; getopt is unavailable on
199 yaz-marcdump reads and writes collection wrapped records.
201 Handle OPAC for record conversion module.
203 Fixes for ICU wrapper.
205 Allow ICU libs to be controlled with --with-icu .
207 --- 3.0.16 2007/11/12
209 Added yaz_poll which is a wrapper for select/poll. When poll is available
210 and non-buggy, it is used, by yaz_poll . This allows more than 1024
211 sockets to be in use.
213 Added ICU wrapper library which exposes ICU http://www.icu-project.org/
214 functionality through an XML based configuration (ICU chain). This system
215 is useful for search facilities such as Pazpar2 and Zebra that needs to
216 perform tokenization of indexed material. The ICU code in a separate
217 library libyaz3_icu.a.
219 Added HTTP tunnel facility for COMSTACK, bug #1752.
220 This is a facility that allows a Web proxy, such as squid, to tunnel
221 Z39.50 traffic. This facility is "transparent" to must applications
222 using YAZ. It's enabled by using pseudo transport connect: followed by
223 the proxy address, followed by command, then follwed by he regular
224 "virtual" addresss. For example,
225 connect:webproxy.com:3128,tcp:z3950.loc.gov:7090/voyager .
227 More MARC-8/UTF-8 conversion fixes. Bugs #1666, #1667, #1778.
229 --- 3.0.14 2007/09/21
231 Fixed bad memory reference in ZOOM_record - cuased by member not being
232 initialized. This was a problem only in YAZ 3.0.12.
234 Fixed bug in conversion from MARC to XML: Non-XML characters in control
235 fields were not removed.
237 Changed the way C code is generated from codetables.xml. Made a MARC-8
238 conversion trie for each characterSet section rather than codeTable.
239 This is ensure the code can deal with G0/G1 sequences. Use of a newer version
240 of codetables.xml from Larry Dixson, LOC. Bug #1464.
242 --- 3.0.12 2007/09/12
244 ZOOM C now handles SRU surrogate diagnostics (i.e. errors returned
245 from ZOOM_record_error).
247 ZOOM C function ZOOM_record_get returns record schema for type="schema".
249 Implemented HTTP Basic authentication to SRU/GET, SRU/POST and SRW requests.
251 Added new ZOOM C connection option 'sru_option' which specifies SRU version.
253 Better SRW-to-Bib-1 diagnostic mapping.
255 ZOOM C and yaz-client announces SRU version 1.2 by default.
257 yaz-client 'sru' command may specifiy both SRU version and transport (SOAP,
260 Fixed in yaz_sru_decode to allow other version than 1.1.
262 --- 3.0.10 2007/08/22
264 Added support for SRU scan for ZOOM.
266 Added support for the use of the older versions or Extended Service
267 Update in ZOOM. To faciliate this, an option "updateVersion" may be
268 set to the version , 1=first, 2=second, 3=third. The third version is
269 what ZOOM C has used so far. And that, obviously, is the default.
271 Added support for CCL queries in Z39.50 queries sent to the GFS (and
272 therefore in Zebra and in SimpleServer-based applications). The new
273 <ccl2rpn> element in a GFS configuration file, if present, names a CCL
274 qualifier file used to transform incoming CCL queries into Type-1 RPN,
275 which is passed into the back-end search callback function.
277 Added support for HTTP Basic authentication in clients: the SRU/W
278 codec encodes the username/password elements of the PDU structure
279 appropriately, and these may be set using the "user" and "password"
280 options in ZOOM-C applications (the same options that are used for
281 Z39.50 authentication).
285 Fixed bug #1208: SSL appears to be broken in ZOOM.
287 Fixed bug #1206: Libxml2 include path weirdness.
289 Added oid_name_to_dotstring.
291 Allow elementSetName to be specified for ZOOM C record update.
293 Allow waitAction to be specified for ZOOM C based for Extended Services.
295 Fixed NULL ptr reference bug in yaz-ztest - caused by omitted record
296 syntax OID. Bug introduced in YAZ 3 series.
298 Updated WIN32 build to include Libxml2 2.6.28 / Libxslt 1.1.19.
302 Fixed bug #1157: yaz-client does not read .yazclientrc from current
303 directory. yaz-client now reads commands from file given by option -f
304 if specified; then tries to read .yazclientrc in current directory.
305 Failing that, it reads .yazclientrc from user's home directory.
307 Added support for correlationInfo Note and ID for Record Update via
310 Added yaz-client command querycharset which specifies character set for
311 query terms for Z39.50 RPN queries and Z39.50 Scan Requests
312 (termListAndStartPoint).
314 Charset ISO5428:1984 is an alias for ISO5428-1984.
316 Implemented a way to perform scan in a result set using Z39.50. This
317 is achieved by attaching the result set name in the characterInfo
318 (type InternationalString) of OtherInformation in the Scan Request PDU.
319 The result set is identified in the otherinformation by the new OID:
320 USERINFO, Z3950_PREFIX.10.1000.81.4, "Scan-Set
321 This allows for scan in result set and faceted search . Zebra did some
322 of this in the APT term using attribute type 8 and value being result
323 set. Using the OtherInformation approach for this is cleaner and easier
324 to work with in proxies and the like. This facility can be used in
325 yaz-client using new command setscan which takes a result set as first
326 argument, start position (APT) as second.
328 Changed decoding of SRU XML packed records to deal with servers that
329 have recordData with XML data with multiple root nodes. Also make
330 comparison for recordPacking case insensitive. Again, one server
331 returns "XML" where others return "xml".
333 For SRU responses allow Content-Type application/xml as well as text/xml.
337 Fixed bug in character set conversion of BER strings. Bug introduced
342 For OIDs use Odr_oid type everywhere, i.e. do not assume Odr_oid=int.
344 For OID class, use oid_class consistently.
346 Fixed external handling for SUTRS and Explain records (bug appeared in 3.0
349 Added partial support for ISO5428-1984, which is the "Greek alphabet coded
350 character set for bibliographic information interchange". By Giannis Kosmas.
352 Added documentation on new OID API.
356 Changes to generic frontend server interface: added new member
357 'query_charset' for bend_initrequest structure. A backend init handler
358 should set this member to its native character set for query terms.
359 When defined, the frontend server logic will announce this character set
360 to a client if the negotiationModel bit is set by the client. All server
361 implementors are encouraged to specify this. If a backend server does not
362 specify this a warning is issued using yaz_log(YLOG_WARN,..).
364 Added CCL utility to remove terms (stop words) from resulting RPN
365 tree. This is handled by functions with prefix ccl_stop_words_ .
367 New ZOOM C option, "rpnCharset", which allows client-side conversion of
368 terms in RPN queries.
370 Clean-up the CCL API. Moved some internal structures from ccl.h to
371 private header cclp.h. Changed ccl_parser_create so that a Bibset must
372 be supplied. Removed tokenize API from ccl.h - including ccl_parser_find.
373 This is replaced by ccl_parser_find_str which takes a string instead.
375 Split YAZ library into two libs : libyaz.la and libyaz_server.la.
376 libyaz.la is the core of YAZ except the generic frontend server and
377 does not depend on POSIX threads anymore. libyaz_server.la is the
378 generic frontend server facilities and uses POSIX thread functionality
379 if available. The libyaz.la no longer depends on POSIX threads because
380 the number of global structures is limited. NMEM no longer re-uses blocks
381 between threads ; it simply free's memory immediately but allocates in
382 "large" chunks as usual. We don't expect any performance penalties
383 because of this. The yaz_log system is still using a global log_level so
384 caution must be taken when modifying it with yaz_log_init_.. +
385 yaz_log_mask_str. This, however, should not cause any trouble because
386 these functions are called during initialization of application code
387 anyway. `yaz-config --libs server` returns libs for server applications;
388 `yaz-config --libs` returns libs for non-server applications.
390 New OID database - with public definitions in oid_db.h. Removed old OID
391 database including the head oid.h and definitions such as enum oid_value
392 and struct oident. The new OID database uses the same string names as
393 before but the 'protocol' is gone. There are now only two representations
394 raw OID (int *) and string. Functions with prefix yaz_string_to_oid
395 converts from string to OID; functions with prefix yaz_oid_to_string
396 converts the other way.
398 Change to emit_term() in CQL-to-PQF query translation: when a term has
399 the /regexp relation modifier, do not process it for leading and
400 trailing "^" and "*", which have quite different meanings in regular
403 Attempted fix of bug #976: Segfault in yaz_iconv. The yaz_iconv function
404 write handlers no longer carries a 'last' parameter. This will make
405 yaz_iconv flush "less" characters. A flush is performed by call to
406 yaz_iconv(cd, 0, 0, &outbut, &outbytesleft) .
408 Definition of wrbuf_diags moved to querytowrbuf.h. Function wrbuf_put_zquery
409 removed, because function yaz_query_to_wrbuf does the same.
411 API changes to WRBUF. wrbuf_free removed; replaced by wrbuf_destroy. And
412 wrbuf_puts no longer appends '\0'. Use wrbuf_cstr to get C-string out.
414 Deprecated MARC utility functions removed.
416 Changed prototype of yaz_marc_decode_buf: const char for result and size_t
419 Branch split: YAZ_2_1_55_branch
421 --- 2.1.54 2007/03/16
423 Fix to ZOOM-C so that transparent reconnection is properly handled on
424 connections that are in asynchronous mode.
426 Fixed compilation on OpenBSD 4.0.
428 Large strings in GRS-1 records are now properly displayed in yaz-client.
430 Added character conversion support for "advancegreek"; based on patch from
433 Fixed yaz_iconv to return YAZ_ICONV_EINVAL if an incomplete MARC-8 combo
434 sequence is met. Before the error was not set so it would be unknown.
436 Adjust yaz-marcdump MARC reader so that it skips until record separator
439 --- 2.1.52 2007/03/07
441 ZOOM-C: Removed hardcoded limit of 1024 sockets in ZOOM_event_sys_poll().
442 Note that ZOOM_event_sys_select() still has the limit due to the fixed-size
443 fd_set structure used as a bitmask for the FDs to be selected on.
445 Using ACX_PTHREAD macro to check for POSIX threads.
447 Fixed have-vsnprintf check.
449 --- 2.1.50 2007/02/23
451 Fixes for configure on BSD. Bug #900.
453 Added snprintf/vsnprintf wrappers for systems that don't have
454 limits (heavens forbid).
456 Fixed bug in ZOOM-C's event and task handling. If a ZOOM task was
457 created before all previous tasks were completed and removed from the
458 task queue, the new task could be removed by a mistake.
460 Fixed bug #615: Document retrievalInfo facilities for Frontend Server.
462 Implemented pass-through CQL-to-PQF conversions. Bug #861.
464 Fixed bug #832: Problem with MARC/charset in yaz-client.
466 Fixed bug #668: save command line history for yaz-client.
468 Fixed bug #830: pkg-config support.
470 --- 2.1.48 2007/01/23
472 Extended ZOOM result set options with two options that may be read by
473 a client: resultSetStatus and presentStatus with values as specified for
475 http://www.loc.gov/z3950/agency/markup/04.html#Search-status
477 Fixed bug #827: Using SSL fails on Debian etch.
479 Fixed bug #826: Weird looking chars for set of MARC records.
481 Implemented alternative Item Order package for ZOOM. If option "doc" is set,
482 that is treated as an ItemOrder with itemRequest being an XML document
483 external. The value of "doc" is the content.
485 Extended the GFS search facility. New member of bend_search_rr
486 'estimated_hit_count' signals that hits is known to be an estmate
487 (higher or lower than real hit count). New member 'partial_resultset'
488 signals that the search was partial (hit count is lower or equal than
489 real hit count). For Z39.50, the information is stored in resultSetStatus
490 member of SearchResponse APDU. For SRU, the information is signalled
491 via SRU diagnostic 59: "Result set created with valid partial results
494 Switched from jade/pdfjdaetex to dblatex for Docbook documentation in PDF.
496 --- 2.1.46 2007/01/13
498 Implemented bug #806: Deal with HTTP clients sending LF in HTTP headers.
500 Added ZOOM_connection_peek_event.
502 Implemented Generic select hook for ZOOM (bug #803). This is achieved with
503 the following new functions:
504 ZOOM_event_nonblock, ZOOM_connection_process,
505 ZOOM_connection_get_{socket,mask,timeout},
506 ZOOM_connection_fire_event_{timeout,socket}.
507 The existing blocking event handler, ZOOM_event, is a wrapper for the
508 + blocking ZOOM_event_sys_{poll,select}.
510 Implemented function ccl_xml_config which parses XML version of CCL
511 configuration (bug #798).
513 Fixed bug #797: yaz_marc_write_xml does not honor character conversion.
515 Added timings utility (yaz/timing.h)
517 --- 2.1.44 2007/01/03
519 Added yaz_marc_write_xml which creates MARCXML/MarcXchange record as
522 Fixed bug #779: Rotation of apdu.log fails.
524 Fixed for character set conversions:
525 Unicode to MARC-8 conversion for certain less preferred UTF-8 sequences.
526 Honor G1 set in MARC-8 decoding.
528 --- 2.1.42 2006/12/17
530 Fixed bug #775: char conversion does not handle Alternative UTF-8
533 Implemented function yaz_marc_read_line which parses MARC line format
534 records. There is a wealth of formats out there. So far, this function
535 reads line records produced by yaz_marc_write_line.
537 yaz-marcdump's options -x, -X, -I, -e have been replaced with the
538 more generic and easier to remember(!) options: -i format and -o format
539 which specifies input format and output format respectively - where
540 format is one of "marc", "marcxml", "line", "marcxchange".
542 Added 'check only' option for MARC utilities. Option -n for yaz-marcdump
543 does not print anything except warnings for records.
545 For yaz-marcdump, added support for MARC split into files (-s) with a given
548 Changed the SRU update structures and codecs to reflect the SRU pre 1.0
549 spec, at http://www.loc.gov/standards/sru/record-update/
550 This has changed the binary layout of the following structs:
551 Z_SRW_extra_record, Z_SRW_updateRequest, Z_SRW_updateResponse and
552 bend_update_rr . Patch by Ko van der Sloot.
554 Added GFS utility function bend_assoc_is_alive which returns 1 if
555 association is still alive (client is connected); 0 otherwise (client
556 closed connection). This allows busy servers to stop working for
559 Added ziffy: the promiscuous Z39.50 APDU sniffer. until now, ziffy has
560 been a separate piece of software. This version of ziffy has been modified
561 to fit with YAZ. ziffy is copyright Rocco Carbone and covered by GPL v2.
563 Fixed bug #740: Handle SRU records referring to xmlns's outside recordData.
565 Fixed bug #722: Allow Z39.50 Init Options to be specified / retrieved.
566 Client code may now interrogate options such as "init_opt_sort" to
567 find out whether the server claims to support various options.
569 --- 2.1.40 2006/11/27
571 Added utilities yaz_{set,get}_esn to set/get element set name from
574 Removed the build of libyazthread.la. The libyaz.so is the threaded version
575 of YAZ and has been so since YAZ 2.1.10.
577 Implemented ZOOM_record_error which returns error information for
578 record (surrogate diagnostic).
580 --- 2.1.38 2006/10/31
582 Updates for SRU Update by Ko van der Sloot:
583 1. Changed name from "operation" to "action"
584 2. Fixed that that "recordIdentifier" was called "recordId". Kept the old
585 versions in the code, marked as 'backward compatible'.
586 3. Added diagnostics for SRU Update.
588 Fixed bug #709: Records are fetched in wrong format when tasks are queued.
590 Fixed bug #707: CQL->RPN ignores lines with leading spaces.
592 Fixed bug #706: XML hex encoding UTF-8 chars out of range 0-255.
594 For GFS, fixed problem with SRU diagnostic 'First record position out of
595 range' being issued for 0 hits.
597 zoomtst10 part of Windows Build.
599 --- 2.1.36 2006/10/13
601 Implemented yaz_filepath_comp which splits a path into file path
602 components (required by Zebra 2.0.3+).
604 Change wording of YAZ license to the 'Revised BSD License'. YAZ has used a
605 BSD inspired license until now so this should not have any real impact on
606 anybody. See http://www.opensource.org/licenses/bsd-license.php
608 Fixed bug #687: Missing log lines.
610 Fixed bug #678: CQL to PQF translation does not preserve double-quote
613 Fixed bug #689: SRU diagnostics to be added.
615 Implemented new ZOOM function, ZOOM_connection_is_idle, which checks
616 whether a connection is idle (no more work do do).
618 --- 2.1.34 2006/10/04
620 Change type of optval from long to int for invocation of setsockopt with
621 the SO_REUSEADDR option. Thanks to Ateeq A. Altaf, Talis.
623 Added support for specifying the max log file size for the Generic
624 Frontend Server. The size is given with option -r.
626 --- 2.1.32 2006/09/21
628 Fix problem introduced in YAZ 2.1.28 WRT unix sockets in the ZOOM code.
630 --- 2.1.30 2006/09/17
632 Fixes for getaddrinfo use, Bugs #655 + #660. These bugs were introduced
635 Fixed bug in Generic Frontend Server that could cause a server to stop
636 accepting new connections. Bug only seen on dual CPU Windows 2003 server.
638 For the generic frontend server, the maximum record size is used as maximum
639 size of incoming packages (SRU + Z39.50). The value until was previously
640 only used in Z39.50 Init negotiation and, later, in a session controlled
641 sizes of records returned. This is controlled using -k option. It can be
642 specified, per server, with element maximumrecordsize in YAZ' GFS XML config.
644 --- 2.1.28 2006/09/04
646 TCP/IP comstack uses getaddrinfo now to resolve names. It should be IPV6
649 Fixed bug #644: Using Non Reentrant gethostbyname causes SIGSEGV.
651 New option for yaz-marcdump -lpos=value which allows setting a portion
652 of MARC header to a certain value.
654 Fixes for MARC generation when encoded as MARC-8 (bug 642, 643).
656 ZOOM-C reads option extraArgs. If set the value of extraArgs is appended to
657 SRU URI (POST/GET). Value must be URL encoded, such as x-id-a=v1&x-id-b=v2 .
659 --- 2.1.26 2006/08/15
661 Fixed problem with SRU mode type (soap, get, post) for yaz-client
664 Fixed problem another problem with ZOOM_EVENT_RECV_RECORD . Bug #626.
666 --- 2.1.24 2006/08/08
668 Fixed MARC ISO2709 encoding routines to deal with character set
671 Minor changes to GFS logging. Database included in search request log
674 Fixes for ZOOM-C: event ZOOM_EVENT_RECV_RECORD was not generated for
675 cached/multiple records.
677 Shared libraries are built by default on Unix+configure.
679 Changed cql2pqf transformation to use a different evaluation order. The
680 new order is: always, relation, structure, position, truncation, index
681 and relationModifier. Old order was: always, relation, relationModifier,
682 structure, index, position, truncation. Note that the the latter ones
683 override former ones for identical attributes.. The new scheme means that
684 it is possible to override any existing attribute with a relationModifier.
685 And also that it is possible to override everything for the index rule
686 (except the ones listed in relationModifier). No order is perfect but this
687 one, we believe, covers more real cases.. The "always" should have been
688 called "default", since the attributes there can be overridden with all
691 For Libxml2 and friends, YAZ defines YAZ_HAVE_{XML2,XSLT,EXSLT) in the
692 compilation phase, but also for yaz-config --cflags output. This allows
693 us to have public headers with Libxml2 stuff in them . It should also,
694 eventually, make Libxml2 checks redundant in packages using YAZ, such
697 --- 2.1.22 2006/06/15
699 Changed SRU update structure bend_update_rr so that SRU diagnostics are
700 stored in uri, message and details.. Previously diagnostics were stored
701 in errcode, errstring. Patch by Ko van der Sloot. Breaks binary
702 compatibility.. but he's probably the only one affected, so.
704 Added support for CCL, compiled on the client side, in ZOOM-C. This
705 is invoked using ZOOM_query_ccl2rpn() with the CCL configuration as
706 input; the resulting query objects can be used for for searching with
707 ZOOM_connection_search() and scanning with ZOOM_connection_scan1().
709 YAZ' configure searches for OpenSSL by default.
711 SSL comstack uses SL_CTX_use_certificate_chain_file rather than
712 SL_CTX_use_certificate_file. See
713 http://lists.indexdata.dk/pipermail/yazlist/2006-June/001615.html
714 for more info. Thanks to Ko van der Sloot.
716 --- 2.1.20 2006/06/02
718 Bug #600: SRU GET, POST support for yaz-client. Introduced
719 command 'sru' which selects method SOAP/GET/POST.
721 Allow missingValueAction to be specified for the sortspec string -
722 function yaz_sort_spec. By default, the missing value action is null.
723 Use ! to specify "abort". Use = followed by stringvalue to specify default
726 Ensured that Present-handler (if defined) is called in GFS before any call to
727 fetch-hhndler. This now includes piggy-backed presents as well as SRW/U
728 searchRetrieve requests.
730 Documentation for YAZ is now based on the Docbook XML/XSLT using
731 xsltproc + N Walsh's stylesheets. It means that the CVS version of YAZ
732 is no longer depending on jade/openjade or docbook-to-man scripts.
733 PDF is no longer part of the distribution - but can optionally be
734 made using DSSSL/jadetex or FOP.
736 Added retrieval handling support in Generic Frontend Server to support
737 conversion between MARC/XML as well as XSLTtransforms. See
738 etc/yazgfs.xml for an example.
740 Added Authentication support to Generic Frontend Server in SRU
741 mode. Authentication using HTTP Basic is supported, as is the use
742 of 'x-username' and 'x-password' parameters in the request itself.
744 Added support for a new character set MARC8s identical to MARC8 except
745 that it converts combined characters to single Unicode characters in the
746 Latin-1 range (when possible).
748 --- 2.1.18 2006/04/24
750 ASN.1 compiler 0.4: generates brief Doxygen file header for
751 generated .h/.c files.
753 Utility yaz_iconv now supports conversion to MARC-8.
755 New facilities for the MARC module. The reading - and writing of
756 content are separate methods for the yaz_marc_t handle. The following
757 read functions are available: yaz_marc_read_iso2709 (Reads MARC in
758 ISO2709 format), yaz_marc_read_xml (reads MARC in MARCXML/MarcXchange
759 format). Write functions have prefix yaz_marc_write_.. The existing
760 utilities yaz_marc_decode_wrbuf and yaz_marc_decode_buf are still
761 available. Removed support for OAI-MARC and simplexml (not the
762 simplexml from PHP5).
764 Added a new ZOOM event type ZOOM_EVENT_END which signals no more events
765 to be returned for this connection.
767 --- 2.1.16 2006/03/31
769 Allow multiple languages and charsets to be specified with
770 yaz-client. Each item must be separated by comma (NO BLANKS). E.g.
771 negcharset iso-8859-1,utf-8
773 Translation of proximity nodes from CQL into PQF now works.
775 Moved to automake 1.8, 1.9.
777 Added function yaz_log_set_handler which allows a log handler to be
778 installed. This handler will be called for all log messages. Output
779 to file is also produced; but that can be disabled by passing NULL
780 fname to yaz_log_init_file.
782 Fixed another problem with MARC-8 -> ISO-8859-1 conversions. Bug #537.
784 For SRW (including GFS), accept application/soap+xml as content-type
787 For GFS in SRU mode, an empty stylesheet in SRU URL (&stylesheet=&)
788 produces NO stylesheet reference even if a default stylesheet is specified
791 --- 2.1.14 2006/03/14
793 Updated Windows package to include yazd.dll + yazd.lib for the
794 Development component.
796 If the environment variable YAZ_LOG is set, then it is used as a
797 string indicating the default level of logging to use if not
798 overridden by calls to yaz_log_init() or yaz_log_init_level(). If
799 it's not defined, then the manifest constant YLOG_DEFAULT_LEVEL is
800 used as before. So, for example, to omit warnings from YAZ logging,
803 cql_transform() now map structure and other attributes before indexes,
804 so that index-specific structures and other attributes can override
805 defaults. So now a combination of mapping specifications such as:
807 index.dc.date = 1=date-modified 4=5
808 does the right thing.
810 cql_transform() now also respects the "always" mapping specification,
811 which establishes an initial set of attributes to be used for all
812 terms except where overridden by more specific attributes associated
813 with the index, relation or modifier.
815 Added SRU-GET and SRU-POST support for ZOOM C. Option "sru" specifies
816 which mode to use; one of "post", "get" or "soap" (SRW, default).
818 Fixes for yaz_iconv routines: changed trie-based character set conversions
819 to use only non-negative values for bit fields due to Sun's C compiler not
820 supporting negative values.
822 Fixed bug in character set conversion yaz_iconv. Some three byte UTF-8
823 sequences where not read correctly. Fix by Rustam Usmanov.
825 Updated win/makefile to use options, settings which makes things
826 compile with VS C 2005.
828 --- 2.1.12 2006/02/01
830 Fixed bug in yaz_oi_update which used incorrect value for categoryValue.
832 In ZOOM socket code, use select instead of poll on MacOSX.
834 ZOOM-C now support client-side compilation of CQL into RPN that is
835 sent to the server, enabling CQL to be used against all Z39.50
836 servers. Use ZOOM_query_cql2rpn() to set the compiled CQL into a
837 ZOOM_query object, and submit it using ZOOM_connection_search().
838 The CQL-to-RPN translation uses a configuration file, the name of
839 which must be specified in the Connection's "cqlfile" option.
841 ZOOM-C also support CQL scanning, via the new ZOOM_connection_scan1()
842 function, which takes as its start-term parameter a ZOOM_query object
843 (which may have had either CQL or RPN set into it).
846 --- 2.1.10 2005/11/29
848 Added ZiNG Update Support. New codecs are defined in srw.h. Extended the
849 GFS to support this as well. Backend handler, bend_srw_update, does the
850 update work. Code contributed by Ko van der Sloot.
852 Allow retrieval of Search Result-1 information in ZOOM by the use of
853 options that are attached to a result set. ZOOM documentation updated
856 Fixed bug #416: First/second comb characters not handled in the MARC-8 to
857 UTF-8 conversion. Patch by Raj Patel.
859 Added option -m to GFS to control formatting of timestamps in log file.
861 Added 'exit' as synonym for 'quit' in yaz-client
863 Added support for specifying SRW resultSetId + resultSetIdleTime in a
864 Generic Frontend Server's search handler. Refer to include/yaz/backend.h
865 for the new members. Patch by Ko van der Sloot.
867 Added support for SRU POST. It is supported for content-type
868 application/x-www-form-urlencoded only. Patch by Ko van der Sloot.
870 Do not build the separate Multi-threaded (MT) library libyazthread.la.
871 Instead make the library libyaz.la multi-threaded. Threading as a whole
872 can still be disabled by configure option --disable-threads. Previosly,
873 with older GLIBCs there were problems with MT libs under Apache. This
874 has now been fixed a long time ago.
876 Fixed bugs in yaz_log that occurred on Sparc Solaris in Multi-threaded
879 CQL module modified to be case insensitive for relations/indexes/operations.
881 Fixed bug in CQL transform code: incorrect value relationModifieder
884 Added 'show all' command for yaz-client which retrieves all results
887 Added new yaz-client, xmles, which takes a (private) OID and
888 a document to be sent as an extended service request.
890 Describe new yaz-client commands wait_response and set_auto_wait.
892 Increase TCP/IP listener backlog from 3 (which I am guessing was
893 copied from the SunOS manual entry way back when) so SOMAXCONN, so
894 that the socket will queue as many incoming connections as it's able
895 to handle ongoing connections. In other words, it will never now
896 refuse a connection that it would be able to handle merely because
897 it's not got around to accepting() enough of the pending connections
898 yet. This is the behaviour anyway under Linux, where the listen()
899 argument is ignored; but not under BSD and on systems such as
900 MS-Windows that use BSD-derived TCP/IP stacks. The behaviour of
901 YAZ-based servers should now be uniform across operating systems in
904 yaz-marcdump uses 64-bit file access on some systems. This is enabled
905 on Linux and other Unix variants where _FILE_OFSET_BITS=64 is supported.
906 This allows yaz-marcdump to read large MARC batches (>2 GB).
908 Modified all YAZ source files - except the source which is auto-generated
909 by tools - to use spaces rather than TABS. Emacs/VIM trailer added to
912 Add ZOOM_connection_option_getl() and ZOOM_options_getl(),
913 corresponding to the existing *_setl() function. These allow option
914 values containing arbitrary valuues.
916 Add ZOOM_resultset_sort1(), which should ALWAYS be used in place of
917 ZOOM_resultset_sort() in new applications. Its behaviour is identical
918 except that it returns an indicator of whether or not the sort
919 criterion was accepted (0 for OK, -1 for invalid).
923 Fixed bug in yaz_marc_decode_buf. By mistake the routine appended
924 MARC output rather than returning "new" buffer.
926 yaz-client warns about unknown init options.
928 Fixed bug #371: "options concurrentOperations ignores concurrentOperations"
932 Added support for SRW sort in Generic Frontend Server. Patch
933 by Ko van der Sloot. Member srw_sortKeys in bend_search_rr holds
934 sortKeys - or NULL if none is provided.
936 Fixed bug #307: It was impossible to specify indefinite/no timeout
937 for ZOOM_event. Special timeout value -1 now means indefinite timeout
940 Added support for multiple languages and charsets to be specified in
941 ZOOM. Each charset/language is separated by a blank. If negotiation is
942 in effect in init-response, Option
943 "negotiation-charset-in-effect-for-records" set to 1(true) or 0(false).
944 Code based on patch by Vasiliy Osadchuk.
946 Fixed bug #306: infinite recursion that occurred when calling
947 yaz_log_level_init as the first call (before other log level or
950 Fixed bug in scan handling in front end server: if preferred-Position-In-
951 Response was non-present, a NULL pointer referece was performed.
955 Changed include/yaz/diagbib1.h and added include/yaz/diagsrw.h with
956 diagnostic messages+codes for Bib-1 and SRW. Preprocessor defines are
957 now defined for all those error codes. So instead of putting 109 in
958 your program you'd use YAZ_BIB1_DATABASE_UNAVAILABLE. The messages
959 are generated from a .csv - file. See src/bib1.csv and srw/srw.csv.
961 Modified the yaz-marcdump utility to skip garbage bytes between MARC
964 Fixed bug - uninitialized memory - due to bad code for fix of bug #272.
966 Program yaz-client now exits and produces an error message if multiple
967 Z39.50 servers are specified on the command line (none or one allowed
970 Program yaz-marcdump skips garbage bytes between ISO2709 records rather
975 Fixed bug #273: Update for recent MARC-8 -> UNICODE changes.
977 Fixed bug #272: Preserve spacing for CCL terms.
981 Added support for virtual hosts and multiple backend servers for
982 the YAZ frontend server. The configution is XML based and
983 support specificition of CQL to RPN mappings and explain information.
984 See section "Virtual Hosts" in the YAZ manual.
986 Extended OPAC display utility. OPAC display utility renders
987 bibliographic (MARC) record as well. Added yaz_opac_decode_wrbuf
988 to supplement yaz_marc_decode_wrbuf.
990 Fixed a bug in MARC decoder that could caused it to crash for some
991 invalid MARC records. More diagnostics and warnings where added in
992 XML output (warnings, etc are stored in comments).
994 --- 2.0.34 2005/02/08
996 Fixes for UNIX domain sockets. Bug #261.
998 Fixes for MARC-8 to UTF-8 conversion. Bugs #258 and #260.
1000 Fixed bug #263: YAZ MARCXML dump shows extra spaces after control fields.
1001 Added yaz_marc_subfield_str which defines subfield lead string which is
1002 used in YAZ_MARC_LINE format. Default string is blank+$. Added
1003 yaz_marc_endline_str which defines end of fields string used in
1004 YAZ_MARC_LINE format. Default string is newline.
1006 Experimental support for MarcXChange. This format can be produced
1007 by yaz-marcdump and is implemented in yaz_marc_decode - functions.
1008 http://www.bs.dk/standards/MarcXchange.xsd
1010 Added yaz-client commands scansize that sets maximum number of
1011 entries to be returned by scan.
1013 --- 2.0.32 2005/01/11
1015 Added support for SRW scan in yaz-client and Generic Frontend Server.
1017 * Added whereInList member to SRW Scan Term.
1019 * Changed Z_SRW_scanRequest to be able to carry both CCL and PQF.
1021 Fixed NMEM system to return aligned blocks on the smallest boundaries
1022 that are suitably aligned for all possible types on the particular
1023 architecture YAZ is being built for.
1025 --- 2.0.30 2005/01/04
1027 Fixed numerious warnings that was issued with newer versions of GCC.
1029 Fixed NMEM system to return aligned blocks on 8 byte boundaries rather
1030 than 4 bytes, since 4 may not be enough on some systems such as GCC 3.4.3
1033 Make YAZ Generic Frontend Server slightly faster.
1035 Enhance (and reduce) logging for Generic Frontend Server.
1037 Revert YAZ log system so that it flushes every write operation
1038 by default. (YAZ 2.0.26 and earlier verisons did that). Bug #240.
1040 Modified the YAZ logging system. The LOG level defines use YLOG_ prefix
1041 instead of LOG_, due to name clash with syslog(3). LOG_ are still
1042 present. New applications should define YAZ_USE_NEW_LOG=1 - this
1043 will effectively disable old definitions.
1045 --- 2.0.28 2004/11/09
1047 Added yaz_log_time_format which specifies log format using
1050 Added yaz_log_module_level which returns mask for a module. Value
1051 is non-zero mask a if module is enabled; zero if disabled.
1053 * Fixed bug #148: CQL parser may leak. A few prototypes were changed
1054 in include/yaz/cql.h.
1056 Fixed bug #176: Dont throw diagnostics on empty SRU args.
1058 Fixed bug #175: surrogate diagnostics in SRW lacking NS.
1060 Fixed bug #172: RPM builds does not enable SSL.
1062 Doxyfile.in part of dist. Doxyfile generated by configure.
1064 Configure aborts if any of --with-xml2, --with-openssl, --enable-tcpd
1065 are given and the corresponding component does not exist.
1067 Extend CCL documentation in YAZ reference. Describe r=r.
1069 --- 2.0.26 2004/10/01
1071 Fixed MARC->MARCXML conversion to properly deal with
1072 fields, subfields, indicators having non-ASCII characters.
1074 Fixed MARC->MARCXML conversion so that ASCII control characters
1075 except TAB,CR,LF are removed from resulting XML (XML 1.0 does not
1078 Added YAZ GFS support for conversion from Z39.50 surrogate
1079 diagnostics to SRW surrogate diagnostics.
1081 Bug fix: YAZ GFS did not return schema in explainResponse.
1083 --- 2.0.25 2004/09/30
1085 The YAZ GFS when converting SRW/SRU requests to Z39.50 structures
1086 now converts recordSchema to elementSetName as well as schema URI.
1088 Fixed bug in COMSTACK that prevented HTTP request packages from being
1091 --- 2.0.24 2004/09/29
1093 Added CCL facility r=r "range" which is similar to r=o "ordered" but
1094 does not require white-space before and after the dash in a range, e.g.
1095 x=-1990 is equivalent to x <= 1990 iff r=r, but equivalent to x= -1980
1098 Fixed a few AC_TRY_LINK configure tests that did not operate properly
1099 due to new GCC removing "redundant" code.
1101 Added yaz-client commands scanpos and scanstep that sets preferred
1102 position and step-size for scan.
1104 Macro YAZ_INIT in yaz.m4: option --with-yazconfig renamed to --with-yaz.
1106 Added CCL utility ccl_qual_buf which parses one or more CCL
1107 spec lines in a buffer.
1109 Added CCL utility ccl_qual_line which adds CCL qualifier line consisting
1110 of name and value - ignoring empty lines and comments.
1112 On Windows, the debug DLL/import lib is now named yazd.{dll,lib}.
1114 Added odr_get_element_path which returns current element path for an
1115 ODR handle. This utility is useful in error handling or user-defined
1118 Added ODR_PRINT utility odr_set_stream which is is a more generic
1119 alternative to odr_setprint. odr_set_stream takes a stream handle, pointer
1120 to a write function and pointer to close function. The close function - if
1121 non-NULL - will be called during odr_destroy.
1123 Fixed bug in CCL parser where truncation char was not removed from
1124 right side when truncation=both was in effect.
1126 Fixed CQL parser to use unsigned chars for isxxx from ctype.h due
1129 --- 2.0.23 2004/08/11
1131 Fix buffer overrun in CQL parser when dealing with proximity (%).
1133 Fixes for MARC-8 in yaz_iconv character set utilies. The MARC-8
1134 to UTF-8/UCS conversion is now only based on codetables.xml.
1136 yaz_marc_decode_buf sets leader pos 9 to "a" for MARCXML output.
1138 --- 2.0.22 2004/08/06
1140 Add support for more "commit changes" in ZOOM (uses Extended Services).
1142 For yaz-client, command set_marcdump <file> / -m <file> dumps SUTRS/XML/..
1145 Yet another small fix for configure of SSL.
1147 --- 2.0.21 2004/05/14
1149 Fix SSL libs for configure when --with-openssl=DIR is given.
1151 --- 2.0.20 2004/05/10
1153 Add autoconf m4 macro YAZ_DOC for YAZ documentation setup (docbook).
1155 SSL comstack now uses yaz.pem certificate file on server side
1156 by default. Certificate filename can be configured by calling
1157 comstack function cs_set_ssl_certificate_file before cs_bind is used.
1159 Fix bug regarding multiple calls to ZOOM_connection_connect.
1161 Implement cs_set_ssl_ctx which sets SSL_CTX for SSL comstack.
1163 Do not create SSL_CTX in cs_create (ssl_type). Create in tcpip_bind,
1164 tcpip_rcvconnect instead. This allows user to set custom SSL_CTX.
1166 ZOOM now allows inspection of X509 peer certificate for verification.
1167 The X509 buffer is retrived by reading ZOOM option "sslPeerCert".
1169 Removed libyazssl.la. When SSL is enabled, libyaz.la has SSL support and
1170 all programs have too (yaz-ztest, yaz-client, zoom..). May not be
1171 as "modular" but it simplifies things.
1173 Added cs_get_peer_certificate to that returns peer X509 PEM.
1175 Added cs_get_ssl that returns SSL handle (SSL *) for SSL comstack; returns
1176 NULL if SSL is unavailable.
1178 Documentation about MARC decoding tools.
1180 Fix --disable-tcpd to really disable tcpd. Patch by Robin H. Johnson.
1182 --- 2.0.19 2004/03/30
1184 Rename CHANGELOG to NEWS to follow GNU style packing.
1186 Fix bug with missing initialization of member in init_diagnostics.
1187 This bug affects threaded version of GFS server.
1189 --- 2.0.18 2004/03/20
1191 Use wrbuf_xmlputs_n instead of wrbuf_write_cdata to avoid clash with
1194 Ensure zlib.dll is packed with Windows install.
1196 --- 2.0.17 2004/03/17
1198 Fix encoding of xsd:string to use text instead of CDATA.
1200 Fix endless loop in CQL parser with unbalanced ".
1202 Use a more compact way to store MARC-8 conversion tables.
1204 --- 2.0.16 2004/03/16 Debian only
1206 Oleg Kolobov Fixed a bug in yaz_iconv regarding conversion to
1209 Update CQL parser to use new CQL 1.1 modifiers for booleans and
1214 --- 2.0.15 2004/03/01
1216 Another fix for decoding of XML packed records.
1218 --- 2.0.14 2004/02/25
1220 Fixes for Chunked encoding. White space not ignored after length spec.
1222 Update NS and use default NS for SRW diagnostic elements.
1224 --- 2.0.13 2004/02/23
1226 Implement ZOOM_resultset_cache_reset which resets record cache.
1228 Implement ZOOM_resultset_sort which sorts a result set.
1230 Implement chunked HTTP transfer.
1232 For SSL, use -lssl -lcrypto on systems that don't have pkg-config.
1234 --- 2.0.12 2004/02/16
1236 Added member 'schema' to bend_explain_rr structure so that backend
1237 can specify explain record identifier. Defaults to Zeerex 2.0.
1239 Fix encoding of OID's of form 1.0.X. Bug introduced in 2.0.11.
1241 --- 2.0.11 2004/02/16
1243 * SRW/SRU 1.1 updates: updated diagnostic in srw.h to use uri instead
1246 Added init command for yaz-client which sends "extra" init request.
1248 Fixed two bugs in OID codec - ber_oidc. Throw error when encoding/decoding
1249 bad truncated OID. Fix decoding of OID X.Y... when X=2 and Y>39.
1251 Fixed a bug in ASN.1 compiler that caused Type-1 Operator codec to fail.
1253 Make ZOOM error code for "invalid query".
1255 Fixed compilation for SSL which wasn't properly enabled for all platforms.
1257 --- 2.0.10 2004/02/05
1259 For yaz.m4, allow second argument for YAZ_INIT to hold minimal version of
1262 * SRW/SRU 1.1 updates. Diagnostic code now a URI.
1264 Added option -p <file> to make Generic Frontend Server to write PID file.
1266 Added option -D to put Generic Frontend Server in background on its own.
1268 Make ZOOM C recognize option "password". If unset, "pass" is used
1269 (for backwards compatibility).
1271 Fixed a bug in Generic Frontend Server that could make it crash if a
1272 client sets characterSetNegotation bit, but didn't pass negotiation stuff
1275 New YAZ client command, zversion, that sets Z39.50 version (1,2,3..).
1276 Must be issued before open, in order to be in effect.
1278 --- 2.0.9-6 2004/01/12 Debian/Windows
1280 Make the SRU server more picky WRT unknown params, etc.
1282 Bug fix: ZOOM scan response didn't return displayTerm - when present.
1284 New YAZ client command, options, that sets Z39.50 options.
1286 New utility functions yaz_init_opt_{encode,decode} to encode/decode Z39.50
1287 options from a string of tokens (one token for each option bit).
1289 Update SRW diagnostic code messages.
1291 --- 2.0.9-5 2004/01/07 Debian/Windows
1293 Handle user defined stylesheet for SRW/SRU.
1295 --- 2.0.9-4 2004/01/06 Debian/Windows
1297 Fix bug in decoding of Content-Length.
1299 --- 2.0.9-3 2004/01/06 Debian/Windows
1301 Fix a bug with decoding of XML packed records.
1303 --- 2.0.9-2 2004/01/05 Debian only
1305 Allow empty ODR (NMEM=0) for odr_oiddup and odr_getoidbystr.
1307 Fix bug in SRW/SRU diagnostics decoding.
1309 --- 2.0.9 2004/01/05
1311 Fixed bug in Generic Frontend Server which could drop records exceeding
1312 preferred message size. Reported and fixed by Irina Dijour.
1314 Fixed calculation of package size for structured records in Generic
1315 Frontend Server. Reported and fixed by Irina Dijour.
1317 Fixed namespace for SRW/SRU diagnostics.
1319 Fixed SEGV in yaz-client that occured for HTTP connection errors.
1321 --- 2.0.8 2003/12/22
1323 * SRW/SRU 1.1. Since the Namespace has changed for SRW/SRU, it means that
1324 this version is incompatible with version 1.0 and older YAZ SRW/SRU
1327 CQL changes to reflect recent changes to the specification:
1328 * Documentation talks about context sets instead of index sets.
1329 * Documentation talks about indexes instead of qualifiers.
1330 * The CQL-to-PQF transformer's configuration file now uses
1331 "index.set.name = <attributes>" instead of the old form
1332 "qualifier.set.name = <attributes>". (Both forms are still
1333 understood but the latter is deprecated.)
1334 * CQL terms with no explicit index specified are now interpreted as
1335 cql.serverChoice instead of srw.serverChoice (which of course
1336 behaves exactly the same.)
1338 --- 2.0.7 2003/12/16
1340 MARC conversion can now generate ISO2709 output in another
1341 character set. yaz-marcdump uses this facility if you invoke it
1344 Added missing C decl macros for include/yaz/{soap.h,srw.h,cql.h}, so that
1345 functions from there can be used from C++.
1347 --- 2.0.6 2003/12/04
1349 Frontend server now transfers memory from decoded packages to stream
1352 NMEM now clears freed blocks with 'Y' (hex 59) to force bad memory
1353 references to show up.
1355 ZOOM-C now supports standard ZOOM option names as described in v1.4 of
1356 the ZOOM Abstract API. The older names for the same options are still
1357 also supported for the benefit of old applications.
1359 ZOOM-C supports "implementationId" and "implementationVersion" options
1360 to go along with "implementationName". These allow the user code to
1361 specify identification strings to be sent to servers.
1362 Add OID for the new ExtLite attribute set.
1364 Add OIDs for NACSIS-CATP, FINMARC2000 and MARC21-fin record-syntaxes,
1365 as requested/supplid by Ere Maijala <ere@atp.fi>
1367 For generic frontend server, reverse the order of
1368 "toolkit-supplied / application-supplied" strings sent as implementationId,
1369 Name and Version. Also, remove the spaces around the slash. This brings
1370 the GFS in line with the behaviour of ZOOM-C on the client side.
1372 Add function ZOOM_scanset_display_term.
1374 yaz-client shows scan displayTerm if present.
1376 Utility yaz-iconv is now installed by default along with the man page
1379 Extend configure check for OpenSSL to use pkg-config where available (such
1382 Incorporate patch by Morten Bogeskov which allows a Unix file socket
1383 server to specify uid/gid/mask for socket using the format
1384 unix:[user=uid,][group=gid,][umask=mask,]file=path
1385 If file= is omitted the existing format is assumed, e.g.
1387 in which case the mask is 0666 (rw for everybody).
1389 Major restructure of YAZ source. All source in libyaz is in src directory.
1390 Programs in client (yaz-client), ztest (yaz-ztest), zoom (zoom programs),
1391 util (utility programs such as ASN.1 compiler, yaz-marcdump).
1393 Added man page for utility yaz-marcdump (used to be called marcdump).
1394 yaz-marcdump is installed by 'make install'.
1396 Fixed a memory leak in Generic Frontend Server that occurred when decoding
1397 of incoming package failed.
1399 Fixed a potential DOS attack vulnerability in COMSTACK/ODR.
1401 Change prototype of odr_perror: add const to message string.
1403 New function yaz_log_reopen which reopens log file (for log rotate, etc.)
1405 * Blocking parameter for COMSTACK cs_create is now a bit mask rather
1406 than a blocking flag. Bit 0 is set for blocking, reset for non-blocking.
1407 Bit 1 is set if cs_addrstr should avoid DNS lookup; reset for full
1408 DNS lookup. There should not be any compatibility problems with this
1409 assuming that blocking=1 or 0 is used.
1411 Fix bad reference in UNIX comstack in function cs_addrstr.
1413 Fix for compilation on AIX.
1415 The generic front-end server (server/seshigh.c) now supports returning
1416 Init diagnostics to the client in User-information-field, in
1417 accordance with Z35.90 Implementor Agreement 5 (Returning diagnostics
1420 --- 2.0.4 2003/09/04
1422 Allow any CQL relation (not just all,any,exact,scr).
1424 Fixes for OCLC UI ASN.1 to make it work with SilverPlatter targets
1425 that features the same UI.
1427 Implemented command update0 in YAZ client which is equivalent to
1428 update but uses old of Ext Update ASN.1.
1430 Use OID 1.2.840.10003.15.1000.81.1 for privately defined charsets
1431 in charset negotiation. Added VAL_ID_CHARSET in oid.h.
1432 Previously no OID was used for this info.
1434 ZOOM uses smallSetUpperBound=1 instead of 0 for piggyback searches.
1435 It apparantely upsets EBSCO Publishing IR Z39.50 Server which
1436 returns 'malformed search term' otherwise.
1438 SortResponse member resultCount now set to NULL in sort handler of
1441 OPAC support ZOOM. ZOOM_record_get returns OPAC info (as XML) if
1444 Add three new utility functions for translating OIDs between various
1445 formats -- symbolic name such as "Usmarc", minus-1-terminated int
1446 arrays and dotted strings such as "1.2.840.10003.9.5.1":
1447 int *oid_name_to_oid(oid_class oclass, const char *name, int *oid);
1448 char *oid_to_dotstring(const int *oid, char *oidbuf);
1449 char *oid_name_to_dotstring(oid_class oclass, const char *name, char *oidbuf);
1451 Reverted modifications for ES Update definition for z_IU0Update
1452 (OID 1.2.840.10003.9.5.1 and 1.2.840.10003.9.5). The definition
1453 is back to YAZ 2.0.2.
1455 String value attributes for CCL parser.
1457 Support for OCLC's locally registered "OCLC-UserInformation" PDU,
1458 which their FirstSearch server returns in Init responses, sometimes
1459 carrying useful diagnostic information when Init fails. This has the
1460 OID 1.2.840.10003.10.1000.17.1 and is defined in the file
1461 "z39.50/oclcui.asn", where its definition is somewhat different from
1462 what OCLC document on their web-site, as required to interoperate with
1465 Support for anonymous authentication in yaz-client. Use the command
1468 * Fix the OID of the Index Data-local "admin" Extended Service from
1469 1.2.840.10003.9.81.1 to 1.2.840.10003.9.1000.81.1. The omission of
1470 the 1000, which indicates a locally-defined OID, was a mistake.
1472 --- 2.0.3 2003/06/20
1474 Fix CCL directive @case handling so that it affects string match for
1475 both CCL keywords and qualifiers.
1477 * ESFormat-Update updates. Packages with OID 1.2.840.10003.9.5.1 and
1478 1.2.840.10003.9.5 are now handled by the same decoder z_IU0Update .
1479 Decoder has been updated with ASN.1 changes as listed in
1480 http://lcweb.loc.gov/z3950/agency/defns/updateES.html
1481 Note that the "latest" DB Update, OID 1.2.840.10003.9.5.1.1 , handler
1482 z_IUUpdate, remains unchanged.
1484 ZOOM_record_get may now return a record in a specific character set.
1485 For type use "form; charset=from[,to]" where form (render, xml, ..) ,
1486 "from" is the character set of record as returned by target. "to" is
1487 the character set to be returned. If omitted, "to" is UTF-8.
1489 YAZ ASN.1 compiler renamed from yaz-comp to yaz-asncomp
1491 New ODR utility, odr_getelement, which returns name of element for
1492 which encoding/decoding failed.
1494 Fixed ODR so that it returns error code OREQUIRED rather than ONONE
1495 in cases where a required element was omitted.
1497 Bug fix: some MARC8 sequences were not converted.
1499 New ZOOM option "step" which specifies number of records to be
1500 retrieved in one chunk. Used in conjunction with "start" and "count".
1502 SRW support for yaz-client. Use scheme http: to use it, e.g.
1505 yaz-client no longer does (un)intelligent character set conversions
1506 by default. Can be enabled with charset and marc_charset commands.
1508 xmalloc trace fix for 64-bit systems such as DEC alpha.
1510 Solaris 2.6 compile fix.
1512 New function, cql_strerror() translates SRW error codes, as returned
1513 by cql_transform_error(), into human-readable English strings. Used
1514 in yaz-client diagnostics when appropriate.
1516 New CQL2RPN query-type for the command-line yaz-client, parses CQL and
1517 converts it into a type-1 query which is sent to the server. This
1518 makes CQL available for use with all Z-servers, as opposed to the tiny
1519 minority that can handle CQL queries themselves.
1521 --- 2.0.2 2003/04/28
1523 New Debian package layout similar to the Redhat Package layout.
1525 New ZOOM events ZOOM_EVENT_RECV_{RECORD,SEARCH} for receiving a record
1526 and search result respectively.
1528 --- 2.0.1 2003/04/25
1530 Redhat package is now several packages: libyaz (runtime libraries),
1531 libyaz-devel (development and documentation, and yaz (utility programs).
1532 Package spec file by Morten Bogeskov.
1534 New member 'schema' in struct bend_fetch_rr which the name of requested
1535 schema (SRW/SRU) for record (or NULL if none was given). The fetch
1536 handler MAY set this to reflect the schema of the returned record.
1538 New member 'display_term' in struct scan_entry. GFS now sets member entries
1539 and allocates scan entries to be filled by user scan handler. In previous
1540 version, entries member was allocated by the scan handler. That still works,
1541 but the GFS will ignore member display_term - assuming it was NOT set by
1542 the handler. The fact that the GFS now allocates the entries both allows
1543 for new members and makes a scan handler easier to write.
1545 Fix CQL lex buffer overflow.
1547 SRW/SRU recordPacking. For SRW default recordPacking is string. For
1548 SRU default recordPacking is string.
1550 SRU protocol support for frontend server.
1552 Fix compile bug for systems that have nl_langinfo but CODESET undefined.
1554 Added missing PQF transform rules for <= and >= . Thanks to Peter Popovics.
1556 Added scan for the ZOOM shell (zoomsh).
1560 * String Identifers for Schemas (Amendment 5).
1561 http://lcweb.loc.gov/z3950/agency/amend/am5.html
1562 Old definition for schema
1563 Odr_oid *schema; /* OPT */
1568 Z_InternationalString *uri;
1569 #define Z_Schema_oid 1
1570 #define Z_Schema_uri 2
1573 * resultCount parameter to Sort Response (Amendment 1).
1574 http://lcweb.loc.gov/z3950/agency/amend/am1.html
1576 Support for SRW 1.0 over HTTP. This is an optional feature and
1577 requires libxml2 to operate. Enable SOAP by specifying --with-xml2
1580 Generic frontend server supports HTTP/SOAP/SRW and Z39.50/BER
1581 on the same port. SRW SearchRetrieveRequests are mapped
1582 to bend_init,bend_search,bend_fetch,bend_close.
1584 Z39.50 Query Type-104 added - to facilitate CQL within Z39.50.
1586 CQL support. Source is directory 'cql'. CQL is supported in ZOOM
1587 (both SRW and Z39.50) and the YAZ client (Z39.50 only).
1589 ZOOM connections are SRW based if schem http is used for hostname
1590 in connect, e.g. z = ZOOM_connection_new("http://myserver");
1591 ZOOM_query may be of type CQL, e.g. ZOOM_query_cql(q, "dc.title=x");
1593 CCL proximity operators !n, %n converts to PQF @prox 0 n 1 2 k 2
1594 and @prox 0 n 0 1 k 2 respectively, meaning: exlusion=false,
1595 distance=n, order=true/false, relation=le, prox unit=word. If
1596 n is omitted, distance 1 is used.
1598 Fixed problem with C compiler include path in wrong order.
1600 For TCP/IP COMSTACK, set recv buffer to an appropriate "large" value
1601 on Solaris. Patch from Ko van der Sloot.
1603 New MARC decode API. All new functions operate on a yaz_marc_t
1604 handle. The most important new functions are: yaz_marc_create,
1605 yaz_marc_decode_{buf,wrbuf}, yaz_marc_destroy, .. to create handler,
1606 decode and destroy respectively. Decoder can produce formats
1607 MARC line, simple XML, OAI MARC and MARC XML (LoC). See
1608 include/yaz/marcdisp.h.
1610 YAZ Iconv utility now supports MARC8 decoding (marc8.c). Converts
1611 to UTF-8, UCS-32, wchar_t or Latin-1.
1613 * Prototypes for yaz_iconv_-functions moved to separate header
1614 include/yaz/yaz-iconv.h.
1616 Make a few private functions 'static' in unix.c. This prevents
1617 duplicate unix_close in PHP with YAZ and imap. PHP Bug 20977.
1619 For ZOOM connection, the options targetImplementation{Id,Name,Version}
1620 are set when Init Response is received.
1622 New function ZOOM_connection_error_x similar to ZOOM_connection_error
1623 but returns diagnostic set as well.
1625 New function yaz_strerror which is a portable wrapper for
1626 strerror/strerror_r/GetLastMessage.
1628 * ZOOM_record_get supports type "xml" in which case MARC XML (from LOC)
1629 is returned for MARC. If type is "oai", then OAI MARC is returned.
1631 Fix creation of lib/yaz-config so it works if srcdir != objdir. Patch
1634 --- 1.9.2 2002/11/26
1636 yaz_marc_decode uses OAI MARC as XML format for ISO2709 records.
1638 Fix bad race conditions on SIGTERM and terminate gracefully in
1641 Move retrieval (data1) module to Zebra since nobody seems to be
1644 Add GRS-1 render for ZOOM using same format as yaz-client.
1646 --- 1.9.1 2002/10/05
1648 Added man pages: yaz-client(1), yaz-ztest(8), yaz(7), zoomsh(1).
1650 Fix broken ESpec handling in data1 module.
1652 SGML reader parses comments and makes them part of the data1 tree.
1654 Added several type casts so that YAZ compiles as C++ code.
1656 ZOOM didn't handle PDU encoding failures properly.
1658 Added more Bib-1 diagnostics (approved extensions).
1660 GNU configure: better check for iconv.
1662 More portable use of accept, getpeername. Check for socklen_t. Use
1663 int/size_t if socklen_t is not defined.
1667 PQF parser rejects bad queries - including those with extra
1668 characters in them. PQF parser used to silently ignore that.
1669 Cleaner API for PQF added, which allows you to get detailed
1670 error information for bad queries (see yaz/pquery.h).
1672 Fixed bug in ZOOM_record_get for type "database".
1674 Implemented mini iconv library supporting conversions between
1675 UTF-8, UCS4, UCS4LE and ISO-8859-1. Implemented in util/siconv.c.
1677 * Removed XML reader (d1_expat.c). It's part of Zebra instead.
1679 --- 1.8.9 2002/08/20
1681 Fixed ZOOM C record cache so that preferredRecordSyntax and
1682 elementSetName is used to check for already fetched records.
1684 --- 1.8.8 2002/08/02
1686 Added three members in bend_initrequest structure to facilitate
1687 character set negotiation.
1689 Fixed a bug in frontend server that could cause indefinite
1690 loops under rare conditions.
1692 Revised character set utilities (charneg.h) so that encoding
1693 UCS-4, UCSA-4, UTF-16 and UTF-8 are encoded non-privately.
1695 For PQF, directive @term <type> sets term type for Scan/Search.
1696 Here <type> is general, string, numeric, null. The term type
1697 is inherited - just like @attr.
1699 New call odr_set_charset that sets character set conversion for
1700 international-strings on a ODR stream. Prototype is:
1701 int odr_set_charset(ODR o, const char *to, const char *from);
1702 The InternationalString is still represented as C string in YAZ
1703 so native strings of type UTF-8, ASCII, etc. will work (UTF-16
1704 won't). On the protocol level, you can use any encoding.
1706 Support for UNIX sockets in ZOOM.
1708 Solaris recv sometimes returns errno == ENOENT. It is treated as
1709 EINPROGRESS. COMSTACK patch by Ko van der Sloot.
1711 New COMSTACK of type UNIX Socket. Use "unix:/path" as address for
1712 both client and server. Code by Morten Bogeskov.
1714 --- 1.8.7 2002/05/22
1716 On Windows ZOOM functions are of type __stdcall rather than __cdecl, so
1717 that they can be used directly from Visual Basic. You must recompile
1718 your windows APP if you're using ZOOM.
1720 Character Set and Language Negotiation(3) for ZOOM API and YAZ client.
1721 Commands "lang" and "charset" sets language and character set respectively.
1722 Options "lang" and "charset" is interpreted by the ZOOM API. Note, these
1723 are not part of the official ZOOM spec) All is due to Oleg Kolobov.
1725 Attributes from multiple CCL fields may be OR'ed rather than merged
1726 using directive "@field or". Fields are still merged by default -
1727 equivalent to "@field merge".
1729 Fixed bug in ZOOM connect that occurred on OpenBSD (maybe others). Patch
1732 Fixed bug in zget for parameter ExtendedServicesResponse.
1736 --- 1.8.6 2002/03/25
1738 Added PQF feature: '@attr type=value' may be written as '@type=value'.
1740 Client displays USR.1:SearchResult-1 (hits per term).
1742 Additional Search Info for search in Generic Frontend Server.
1744 Fixed CCL parsing of "field=s".
1746 WIN32 installer - using the excellent NSIS software from nullsoft.
1748 Fixed CCL parsing of "field = - <number>".
1750 Added function yaz_marc_decode that decodes MARC for line mode
1751 display or XML (similar to that used by JZKit).
1753 Fixed BER decoding of OPTIONAL CHOICE. The bug didn't affect the
1754 Z39.50. But ISO/ILL was, however.
1756 Added patch by Rustam T. Usmanov that implements Z39.50 duplicate
1757 detection service (Z39.50-1995 Amendment 2) and Language Negotiation (3).
1759 http://lcweb.loc.gov/z3950/agency/amend/am2.html
1760 http://lcweb.loc.gov/z3950/agency/defns/charneg-3.html
1762 --- 1.8.5 2002/02/03
1764 New YAZ client features: Command completion and new commands:
1765 push_command, set_apdufile, set_marcdump, set_cclfields, register_oid.
1766 Code provided by Jacob Poulsen.
1768 New call oid_trav, that visits all registered OIDs via callback.
1770 Function ZOOM_record_get now returns const char pointer rather than
1771 void pointer. It saves a lot of type casts.
1773 For YAZ client, command "auth" now allows you to set authentication
1774 in IdPass style. It is enabled when three tokens are given - order
1775 is user, group and password.
1777 Fix memory leaks in MARC record handling for ZOOM.
1779 New option for YAZ client, -k <kilobytes> that sets
1780 maximum record size. Similar to -k option for generic frontend
1781 server and yaz-ztest.
1783 More fixes for scan. Non-zero stepSize handled. OID's fixes.
1785 Prefix query parser reports "fail" when bad attribute set is given.
1787 Fix in MARC decoder. Proximity logging. Fix for attribute set
1788 in scan handler for server. Patches by Shigeru Ishida.
1790 SSL/COMSTACK updates. cs_rcvconnect completes SSL handshake. ZOOM
1793 Configure option --with-openssl=<dir> now works when a directory is
1794 specified. Patch provided by Morten Bogeskov.
1796 New option for YAZ client, -u <auth>, that sets authentication.
1798 ZOOM fix: error information was sometimes "missing", since error
1799 was cleared/reset too when it shouldn't.
1801 ZOOM_record_get returns ISO2709 buffer when "raw" is given.
1803 --- 1.8.4 2002/01/04
1805 Scan for ZOOM API. New object ZOOM_scanset. New functions
1806 ZOOM_connection_scan, ZOOM_scanset_size, ZOOM_scanset_term and
1807 ZOOM_scanset_destroy.
1809 New ZOOM function, ZOOM_connection_last_event, that returns type
1810 of last event (such as "receive data", "send data", "apdu received",
1813 New ZOOM option, schema, that specifies schema for retrieval.
1815 New CCL feature. Qualifiers can be aliases for one or more
1816 other qualifiers (if more than one is given, OR is used).
1818 ZOOM uses named result sets if target supports it.
1820 Two new YAZ client commands: . (dot, which sources a script of YAZ
1821 client commands), and ! (to execute shell command.). Implemented
1824 Working on Debian packages.
1826 --- 1.8.3 2001/11/19
1828 YAZ client enables named result sets only if target supports it.
1830 *** ZOOM. Prefix for ZOOM definitions changed from Z3950_ to ZOOM_.
1832 * ZOOM. Removed Z3950_connection_host. Use Z3950_connection_option_get
1833 with key="host" to get same result.
1835 * ZOOM. Added Z3950_record_clone and removed Z3950_resultset_get.
1836 Function Z3950_resultset_record(s) returns references to records
1837 "owned" by resultset. To become owner use Z3950_record_clone.
1839 Function z_ext_record handles Extended Services. Thanks to
1842 --- 1.8.2 2001/11/12
1844 CCL Parser fix: ignore token comma when dealing with and-lists.
1846 Documentation updates for COMSTACK.
1848 * ZOOM changes. Query object renamed from Z3950_search to Z3950_query.
1849 Changed prototype Z3950_records. For some functions, int parameters
1850 were changed to size_t.
1852 TCP/IP COMSTACK no longer uses getprotobyname to avoid memory leak
1855 New MARC decode/display function, marc_display_exl, which properly rejects
1856 non-ISO2709 records. YAZ client uses it.
1858 --- 1.8.1 2001/10/29
1860 Fix bug: local attribute set wasn't set correctly in PQF strings.
1864 * Old Z39.50 codecs no longer supported.
1866 Added ZOOM C binding. See http://zoom.z3950.org/
1868 Renamed states for COMSTACKs to avoid confusion with events.
1870 Implemented cs_look and proper cs_rcvconnect.
1872 Fixed COMSTACK error that occurred on HPUX. Fix by Giannis Kosmas.
1874 Configure detects POSIX threads on OpenBSD.
1876 When sort flag 'i' was specified in yaz-client the caseSensitivy flag
1877 was set to a wrong value. Thanks to Robert Sanderson for reporting this.
1879 When error is returned from present handler, non-surrogate diagnostic
1880 is returned in present response (and fetch handler is no longer called).
1882 * Minor adjustments to pquery parser (PQF). Token characters may be
1883 escaped by using backslash (C-style).
1885 PQF parser allows string attribute values to be specified. For @attr,
1886 non-numeric characters after the equal-sign are treated as strings
1887 (e.g. @attr 9=title).
1889 CCL trunction character may be defined (@truncation in file)
1891 * function zget_ExtendedServicesRequest sets waitAction to
1892 waitIfPossible (was wait).
1894 Added cs_set_blocking to set change blocking mode of a COMSTACK. Thanks
1897 CCL operator names may be set in field definition files (CCL_bibset).
1898 See ccl/bib1 for an example.
1900 Fixes in ASN.1 compiler for C++ compatibility.
1902 * Renamed members "and" and "or" in struct Z_Operator to "op_and"
1903 and "op_or" to avoid conflict with C++.
1905 Fixed problem with GNU readline detection on Redhat 7.0.
1907 Added step-size for Scan backend handler.
1909 Fixed bug that made the frontend server crash when no attribute
1910 set was specified for scan.
1912 Front-end server automatically switches to original working directory
1913 when installed as an NT service. Previously -w had to be specified to
1916 Added extended attributes for retrieval module (data1), so that data1
1917 records carry d1_readXML/SGML attributes. d1_read also supports
1918 null-data rules ( <tag/>)
1920 On UNIX when POSIX threads are available, a separate library libyazthread
1921 is created. Programmers should link with that library and the yaz library
1922 when using threads. The reason for the split was that some applications
1923 on Linux, such as Apache, doesn't work well when using shared objects that
1926 Added SSL support for the COMSTACK. You start yaz-client and yaz-ztest
1927 (or any frontend server) in SSL mode by specifying ssl: followed by
1928 address. Only tested on UNIX.
1930 Added feature for CCL module. Virtual structure s=al or s=ol generates
1931 and-list and or-list respectively instead of phrase search.
1935 * Added prefix "yaz_" for the functions log_init.., log_file.. and
1936 log_mask_str. This was done to avoid name conflicts with other libraries
1937 (such as other PHP extensions).
1939 Added raw OID member for preferred record syntax (request_format_raw)
1940 and returned record syntax (output_format_raw) for backend fetch method.
1942 Config file yaz-config now accepts options so that it returns specific
1943 compile settings, etc. Thanks to Morten Bogeskov <morten@bogeskov.dk>
1945 Shared library support for UNIX using GNU libtool.
1947 * Modified backend interface. Request/Response struct's replaced by
1948 one read/write C struct. For example bend_fetchrequest and
1949 bend_fetchresult have been replaced by single bend_fetch_rr struct.
1950 Every handler - even search has to be registered in bend_init
1951 handler. This means that the YAZ library no longer refers to
1952 external functions and it makes it possible to make the whole
1953 thing a single DLL/SO.
1955 Added Segment handler for backend server.
1957 Added Zmbol/Zebra administrative functions to YAZ client.
1959 Threaded frontend server on UNIX (when POSIX Threads are available).
1960 Starting the server with option -T enables multi-threading.
1964 Added configure option --enable-comp/disable-comp to control use
1965 of YAZ ASN.1 compiler. Use --disable-comp to use the old *coders
1966 located in sub directory asn.
1968 YAZ ASN.1 compiler renamed to yaz-comp in sub directory. It's installed
1969 in ${exec_prefix}/bin along with the other programs yaz-client and
1972 GNU automake used to maintain makefiles.
1974 Added several OID's.
1976 Changed retrieval module so that we can load records with no abstract
1977 syntax defined. Tagpaths in these records are fully composed of string
1980 Implemented ISO ILL protocol. Refer to stuff in sub directory ill.
1984 On UNIX, the generated makefile now supports a proper 'make install'.
1985 The prefix can be set via GNU configure to set the install location
1986 (default is /usr/local).
1988 * YAZ programs client and ztest were renamed to yaz-client and
1989 yaz-ztest to avoid conflicts when users install YAZ in "standard"
1990 locations, such as /usr/bin,/usr/local/bin,etc.
1992 * YAZ Header files were moved from include to include/yaz. YAZ Header
1993 files are referred to as include <yaz/log.h> rather than <log.h>.
1994 The YAZ include path (-I ..) is therefore the same as before. Programmers
1995 should update their #include statements or use -Ipath/include/yaz
1996 instead. The main motivation for doing this change is that YAZ header files
1997 can be installed in "standard" locations /usr/include,/usr/local/include
1998 without introducing conflicts, since ALL YAZ header files are stored
1999 in subdirectory yaz (under /usr/include for example).
2001 Compilation of YAZ for WIN32 is now handled by an nmake-style makefile
2002 rather than project/workspace files. We switched because project files
2003 are incompatible between Visual C++ 5 and 6. Refer to windows.txt for
2006 Changed name of logging function, logf, to yaz_log, to prevent name
2007 clash with some math-log functions. The YAZ header log.h defines logf
2008 to yaz_log (#define) so there should be no incompatibilities by this
2011 Added bend_start/bend_stop handlers for server. These handler are
2012 called on start/stop of server. For windows they are called whenever
2013 a service is started/stopped.
2015 * YAZ now auto-generates decoders/encoders for the Z39.50 protocol using
2016 a fairly small ASN.1 compiler written in Tcl. The compiler is located
2017 in util/yc.tcl. The auto-generated C code structures are, in a few
2018 cases, incompatible with the old decoders. There are differences in the
2019 following C structures Z_DiagRec, Z_External, Z_SortRequest, Z_SortResponse,
2020 Z_AttributesPlusTerm, Z_ProximityOperator, Z_DefaultDiagFormat.
2021 The preprocessor variable ASN_COMPILED is defined when the compiled
2022 ASN.1 is being used. Encoder/decoder routines as well as the Z39.50
2023 protocol ASN.1 is located sub directory <tt>z39.50</tt>. If you
2024 wish to use the old encoders/decoders you can specify --disable-yc
2027 Assigned OID for old DB Update (VAL_DBUPDATE0). Updated YAZ compiled
2028 version so that it supports both new - and old version of DB Update
2030 * Added 'name' parameter to ODR encoder/decoder routines to facilitate
2031 pretty ODR print. Updated whole Z39.50 encoder/decoder to reflect the
2032 change. The name parameter can be set to 0 in which no name is specified
2033 for the construction. The macros odr_implicit and odr_explicit sets name
2034 parameter to zero for the construction involved. New macros
2035 odr_implicit_tag and odr_explicit_tag are similar to the others,
2036 except that a name parameter is added. For programmers' that don't use
2037 ODR they probably only need to change the call to z_APDU and z_External.
2039 Added access control facility by interfacing the TCP wrapper library.
2040 YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
2041 tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
2042 name of the daemon and enables the access control as specified in
2043 hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
2045 Fixed memory leak in ccl_find_str and ccl_qual_rm. Thanks to Hans van
2046 den Dool <H.M.vdnDool@kub.nl>.
2048 Added reference ID parameter to most functions in server API - refer
2049 to backend.h. Thanks to Hans van den Dool <H.M.vdnDool@kub.nl>.
2051 Changed name of ccl library to libccl.a (was ccl.a).
2053 Fixed bug in decoder for Explain (Category TargetInfo).
2055 Added support for GNU readline in client. Thanks to Jacob Poulsen
2056 <ja7@dbc.dk>. GNU configure attempts to detect if readline is available.
2058 * CHANGED DEFINITION OF ES: UPDATE (INCLUDING THE OID) to reflect the
2059 new definition from the ZIG. NOTE THIS IF YOU HAVE AN UPDATE
2060 IMPLEMENTATION! This change was made to the development version before
2061 the ZIG decided to retract the amendment. If any users MUST be
2062 compatible with the original Update definition, PLEASE CONTACT US, and
2063 we will include a separate definition corresponding to the old Update
2064 ES. Note that because of the change to the ASN.1 of the
2065 TaskPackageRecordStructure we cannot define a single structure that
2066 will support both versions.
2068 * Added const modifier to buffer parameter for some ODR/BER encoding
2069 routines: ber_dectag, ber_declen, odp_more_chunks, completeBER,
2070 completeWAIS, odr_dumpBER.
2072 Fixed bug in client.c which caused a crash when a scanResponse didn't
2073 contain positionOfTerm.
2075 * Fixed inconsistency in the ScanResponse/ListEntries protocol. This
2076 * will cause an error in a client if a non-YAZ target sends both a
2077 * list of Scan entries and non-surrogate diagnostics.
2079 Retrieval module enhancements. Tag sets may be typed in the reference
2080 to it. From the .abs-file the "tagset" directive takes a third optional
2081 integer type for the tag set referenced. From a .tag-file the "include"
2082 directive takes a third optional type as well. The old "type" directive
2083 in the tag set itself is still recognized but acts as the default type
2086 Backend interface change. Individual Scan terms returned from bend_scan
2087 may also be tagged as Surrogate Diagnostics. Refer to struct scan_entry
2088 in include/backend.h.
2090 Retrieval module enhancements. Multiple tag sets and attribute sets may
2091 be specified in abstract syntax specs. Revised the error/warning for
2092 logging messages reported by the retrieval module when reading the
2095 Object Identifier system (oid_..) changed. The API is backwards
2096 compatible but the oid-routines now allocates new OID's when needed.
2097 Raw OID's may be specified in oid_getvalbyname.
2099 YAZ now uses GNU configure to generate Makefile(s).
2101 * Minor changes in some of the member names of DeleteResultSetRequest and
2102 DeleteResultSetResponse. See include/proto.h.
2104 * Changed some C definitions regarding EXPLAIN record syntax (prt-exp.h)
2105 and added member 'languages' in TargetInfo (which was missing).
2107 Changed the way attribute sets are handled in the retrieval
2108 module. These are now cached, just like the abstract syntaxes
2111 Changed YAZ so that it links with compiled ASN.1.
2113 Added Explain-schema definitions and mapping routines. The following
2114 Explain categories have been implemented: AttributeDetails,
2115 AttributeSetInfo, DatabaseInfo, CategoryList and TargetInfo.
2117 Fixed minor bug in Windows version of Server Library.
2119 --- 1.4pl2+ 1998/4/17 (Released with Zebra)
2121 Added Extended Services to server (backend.h). Thanks to Charles Woodfield.
2123 Added EXTERNAL: UNIverse Resource Report (non-standard).
2125 Implemened odr_enum and odr_set_of functions to handle ASN.1 types
2126 ENUMERATED and SET OF.
2128 * Added 'const' to some of the char pointer arguments for the
2129 functions, data1_read_node, data1_getelementbytagname,
2130 data1_insert_taggeddata, data1_getesetbyname, data1_getelementbyname,
2133 Fixed bug in data1_insert_taggeddata - the last_child member of
2134 parent wasn't initialised.
2136 * Changed data1_read_record and data1_read_node so that the supplied
2137 "SGML"-buffer is read-only. In particular the resulting data1 - tree
2138 doesn't refer to any parts of the "SGML"-buffer.
2140 Fixed bug in server library (Windows version of statserv_remove).
2142 * Changed code so that it compiles as C++. The type definition
2143 of Odr_fun which is a member of Odr_arm was changed. The result is,
2144 that an explicit typecast is needed for the fun pointer when
2145 using Odr_arm - as in:
2146 {1, -1, -1, Z_IdAuthentication_idPass, (Odr_fun)z_IdPass},
2148 Updated TagSet-G and -M definitions (tagsetm.tag and tagsetg.tag).
2150 Implemented the new structured date and time definition as approved
2151 by the ZIG. Added schemaId element to the specificTag in Espec-1
2152 (also approved at the last ZIG). Thanks to RVDM.
2154 Added some Object identifiers (RVDM).
2156 Changed the Update Extended Service (RVDM).
2158 Added command "refid" to client which specifies referenceId for
2159 the following requests.
2161 Implemented extended service handling for server. See ztest.c
2162 for an example as well as backend.h. New handlers are registerd
2163 in the Init handler.
2165 * Changed interface for sort in server.
2167 Added new members to statserv_options_block. It allows a server
2168 to read options from another source than just the command line. Thanks
2169 to Charles Woodfield.
2171 * Changed definition of Z_Triple in file prt-grs.h - member boolean
2172 renamed to zboolean. Some C++ compilers complained about the name.
2174 Minor changes to gils.abs. Added index 's' (sort) on title
2175 and date/time-last-modified.
2177 --- 1.4pl2 1998/1/30
2179 Fixed bug in server library regarding inetd mode (-i). This bug
2180 was introduced by release 1.4.
2182 --- 1.4pl1 1998/1/29
2184 Added sort facility in client and backend server interface.
2186 Fixed problem with dependencies in Makefile(s).
2188 Fixed bugs for encoders/decoders of extended services and
2191 Implemented sub-tree feature for schemas. Sub-trees are
2192 referenced in *.abs-files. See explain.abs for an example
2193 of the use of this feature.
2195 Modified bib1.att; local attributes for ANY didn't include
2196 ANY itself (only affects use of the retrieval module).
2198 Fixed bug in plain SGML reader in function data1_read_node:
2199 tags with prefix "var" was incorrectly interpreted as variants.
2201 Added feature "sub-schemas" to enable references to - and definitions
2202 of - group of elements.
2204 * Removed member parent from type data1_element (in data1.h).
2206 Implemented function odr_nullval() that returns the value of
2209 * Removed member num_children from data1_node (in data1.h).
2211 Made NT service interface part of the server library. The
2212 function statserv_main uses the NT service when required and
2213 calls the statserv_start / statserv_close routines.
2215 Routine zget_SearchRequest and zget_PresentRequest fills
2216 resultSetName/Id member with "default" instead of "Default".
2218 Fixed memory leak in server. Request queue member wasn't freed.
2220 Fixed nmem_exit so that memory is freed.
2224 Revised the CCL parser utility to be thread safe.
2226 Added function, oid_ent_to_oid, to replace the function
2227 oid_getoidbyent, which is not thread safe.
2229 * Added nmem_init and nmem_exit to initialize and release
2230 NMEM resources. Function nmem_init should be called once in the
2231 initial thread before NMEM/ODR is used. statserv.c and client.c
2232 have been changed accordingly. The change was necessary to make
2233 NMEM thread safe. The NMEM memory pool is shared amongst threads
2234 in a process. Unix-based applications will still work fine without
2237 Added NT Services interface for the the Z39.50 (statserv) Server.
2238 Refer to the ztest.c source on the usage.
2240 Windows 95/NT port using MSVC5.0. Project files are included in the
2243 * Defined new 'global' handle for the retrieval (data1) system. The
2244 new handled, data1_handle, describes the state of the data1 system.
2245 This handle is passed as first argument to virtually all
2246 data1 related routines. The functions data1_create and data1_destroy
2247 creates and destroys a data1 handle respectively.
2249 Added ODR encode stream member to all backend request structures
2250 init, search, scan etc. This stream should be used to allocate all
2251 memory used for the response when thread safe operation is needed.
2253 Changed the comstack utility, cs_addstr, to be thread safe. The
2254 returned hostname string returned by the function is now part the
2257 Added comstack utility, cs_straddr, which replaces the tcpip_strtoaddr
2258 function. The cs_straddr takes a COMSTACK handle as argument, so this
2259 function must be used after cs_create and before bind/connect.
2260 This function is thread safe.
2262 Moved test server to 'ztest' directory - generic server code still
2263 in 'server' directory.
2265 Made prefix query (pquery.c) utility thread safe.
2267 Added new function modifier YAZ_EXPORT to 'export' public DLL
2268 functions when using windows (see include/yconfig.h).
2270 Added definitions to the OID database (util/oid.c) (RVDM).
2272 Added new BIB-1 diagnostic messages to the handler diagbib1_str.
2274 Added call to ccl_rpn_delete in client program.
2276 Added ODR argument to ccl_rpn_query and ccl_scan_query to provide
2277 release of RPN structure.
2279 Added support for C++, headers uses extern "C" for public definitions.
2280 With input from RVDM.
2282 In handling of SEQUENCE OF: Counter set to zero when SEQUENCE OF is absent.
2283 Thanks to Ronald van der Meer (RVDM).
2285 Added initializers (zget_ routines) for a number of PDUs. Thanks to RVDM.
2287 Added support for private extensions to the OID database
2288 (oid_setprivateoids()). Thanks to RVDM.
2290 Added optional, physical ANY (key replication)
2292 Fixed null-reference problem in GRS-1 output filter.
2294 Proximity operator added to Prefix Query Format (PQF).
2296 In test client command "base" accepts multiple databases.
2298 Fixed bug in cs_close stack that caused trouble with WINSOCK.
2302 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
2304 Smallish bug-fixes in the new encoders/decoders (explain).
2306 Bug fixed in DeleteRequest.
2308 Fixed tagging bug of type 101 query in SearchRequest-Query PDU encoder/decoder.
2310 Fixed tagging bug in ResourceReportResponse PDU encoder/decode.
2312 Added SOIF syntax (using private OID for now) to retrieval module and client.
2314 Added Update extended service.
2316 Added SearchResult-1 additional info structure.
2318 Added optional CCL (ISO8777) interpreter as separate module. Available
2321 --- 1.2 1996/6/10 (1st anniversary release)
2323 Added Summary record syntax. Lightly tested.
2325 Added OPAC record syntax. Untested.
2327 Added ResourceReport service encoders/decoders. Untested.
2329 Fixed bug in z_Unit - wrong tagging on unitSystem.
2331 Fixed bug in the DiagRecs decoder.
2333 Added options for max PDU size and session timeout to frontend-server.
2335 Added documentation of query-language parsers and other supporting utilities.
2337 [frontend-server] Added Attribute set to the bend_scanrequest API.
2339 [frontend-server] NextResultSetPosition was sometimes set incorrectly when
2340 surrogate diagnostics were generated.
2342 [retrieval] Allow multiple local values for attribute.
2344 [retrieval] Allow multiple attributes per element in .abs files. index type.
2346 [retrieval] Added Summary tagset, abstract syntax, and d1-node/ASN filter.
2348 --- 1.1pl2 1996/4/10
2350 Minor changes, mostly specific to Zebra's requirements (retrieval)
2354 Repaired bug in frontend server when running multiple listening
2355 endpoints in dynamic mode.
2357 z_External() now won't break if a known, ASN.1 value comes encapsulated
2358 in an octet-string. The value will pass through unmodified in an Odr_oct.
2360 Added a bit of code to the demo client to decode & display
2361 ASN.1-structured records represented in the octet-aligned branch of
2362 the EXTERNAL CHOICE. Thanks to CAS for prodding us to finally do this.
2364 Added z_ext_getentbyref() to the ASN module. Doc updated.
2366 * Completed the SCAN definition in the ASN module. This may break SCAN
2367 code based on older YAZ-versions at compile-time. The fix is easy -
2370 * Added 'displayTerm' and OtherInformation to the TermInfo structure
2371 under the SCAN definition. Remember to initialize this, server-people.
2373 Comstack should now support the WAIS protocol in TCP/IP mode. Note
2374 that this does not extend to ODR and ASN.
2376 Comstack allows insertion of established socket (primarily for
2377 inetd-operation of servers). Doc updated.
2379 Front-end server can now start from the inetd in TCP mode. Doc
2382 --- 1.0pl4 1996/1/24
2386 Fixed small problem in SUTRS-filter. A newline was sometimes inserted before
2387 the rank and record number.
2389 Adjustments to the frontend server.
2391 Fixed diagnostic BER dumper. It ignored the file argument.
2395 Various changes to retrieval module.
2397 Changed the union discriminators of the protocol files from enums to
2398 ints paired with #defines.
2400 *Changed oident.class to oident.oclass to avoid a reserved word in C++
2403 *Changed operator in the RPN structure to 'roperator', again to avoid a
2406 Fixed problems in Explain decoders/encoders.
2408 --- 1.0pl2 1995/12/6
2410 Memory bug in log module fixed.
2412 --- 1.0pl1 1995/12/5
2414 Occasional malloc() of 0 bytes fixed in d1_espec.c.
2416 Bug in Explain DatabaseInfo module fixed.
2418 Some '\r' snuck into one or two of the ret'l config tables. A curse on Windows.
2422 The shift to v1.0 signals that we now consider the *core* functionality
2423 of YAZ reasonably stable (the core being more or less equivalent to
2424 Z39.50-1992). Some of the really nifty v3 stuff is still not heavily
2425 tested (Explain not at all - though that will happen soonish).
2427 Minor changes to code to support Windows port.
2429 Various minor changes after we're getting to use GRS-1 & co. more.
2431 Added Espec-1 format.
2433 Added VisibleString field body type to GRS-1. It is illegal acc. to my copy
2434 of the protocol and it cannot be selected when encoding (maps into 'string'
2435 when decoding). Needed to talk to some servers.
2437 Demo client can request simple element set names.
2439 Added Diagnostic Format encoders/decoders.
2441 Added simple Close handling to frontend server (no hooks for resource
2442 reporting yet), and demonstration client.
2444 Added cs_addrstr() command to COMSTACK to retrieve peer hostname/address.
2446 --- 1.0b3 1995/08/24
2448 Fixed bug in the frontend-server. The numberOfRecordsReturned field was
2449 handled incorrectly when records were requested in the searchResponse. This
2450 will only affect you if you use the frontend-server.
2452 Added GRS-1 encoders/decoders to the service-level API. Lightly tested.
2453 Test-client will ask for and print GRS1. Ztest will return dummy records
2456 Added Explain encoders/decoders to the service-level API. Untested.
2458 Added Extended Services: Item Order encoders and decoders to the Service-
2459 level API. Untested. We could use a recent copy of the pertinent bits
2460 of the ILL protocol to add those bits.
2462 Added diagnostic format 1 encoders/decoders to the service-level API.
2465 Moved pretty-printing of structure-wrappers ({..}) from odr_seq.c to
2466 odr_cons.c, which causes a more correct output.
2468 Fixed handling of searchRequest in frontend server. NextResultSetPosition
2469 was always set to 0 when no records were requested in the searchRequest.
2471 * Added better external-handling. This shouldn't harm old code that
2472 *encodes* externals. It can break code that looks for a
2473 'single-ASN1-type' representation, since those types that are known
2474 are now decoded immediately. Look at the SUTRS sample code in
2475 seshigh.c and client.c. Documentation updated.
2477 Handling of structured records in bend_fetchresponse. Length -1 marks
2478 structured record, type is deduced from format field.
2480 --- 1.0b2 1995/06/27
2481 Fairly quick maintenance release to add SUTRS support.
2483 Fixed handling of SUTRS records in the demonstration client.
2485 * Added format field to the bend_fetchrequest and bend_fetchresponce
2486 structures of the backend API (frontend server). When the record is
2487 returned, the value of the format field is mapped to an OID. The
2488 value VAL_SUTRS will also cause a slightly different ASN.1 packaging
2489 of the record. The special value VAL_NONE in the bend_request means
2490 that no specific format was requested by the client. Documentation
2491 updated accordingly. Test server (ztest) will return a fixed dummy
2492 SUTRS record if your client requests SUTRS.
